Letters Patent No. 113,443, dated April 4, 1871.

IMPROVEMENT vHSL FLOUR-SIFTERS.-

The Schedule .referred to in these Letters Patent and making part'of the same.

To all whom it may concern:

Be it known that I, OLIVER D. MYERS, of Doylestown, in the county of Bucks land in the State of Pennsylvania, have invented certain new and useful Improvements in Flour-Sitters; and do hereby declare that the following is a full, clear, and exact description thereof, reference beinghad to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

rlhe nature of my invention consists in the construction and arrangement of a flour-sitter. as will be hereinafter morelnlly set forth. l

In order to enable others skilled in the art' to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a longitudinal vertical section of my iionr-siftcr; and

j `Figure 2 is a side view of a cam cog-wheel used in the same.

A represents a box of any suitable dimensions and shape, provided with a funnel or hopper-,shaped bottom, B, through which the sifted our falls into a pan the teeth a a when the cylinder is revolved, so as to mash up any lumps that may be in the our before it passes down on to the sitter.

One of the journals of the cylinder E extends bcyond the box A, and is provided with a pinion, G, which gears with a cog-wheel, H, mounted on a journal on the end of the box, said wheel being provided with a. crank, I, for turning the same.

1 The flour being placed-in vthe hopper I), andthe lumps separated by the teeth a a', the our falls down on the sitter J, within the box A, said sifter resting and moving` upon cleats or ways d Zin the sides of the box.

In one end of the sifter J is a pin, f, which passes through thc side ofthe box A, and into the cog-wheel H, while another pin, g, attached to the opposite end ot' the box A, passes through the opposite .end of the sifter, this latter pin gA being surrounded by a spiral spring, h, between the box and sitter.

The cog-wheel H is cast with one, two, or more cams or inclines, 7c, against which the outer end of the pin f bears. Now,l as the wheel H is revolved, these cams one after the other will force the pin j inward, moving the sifterJ to the opposite. end of the box,l and compressing the spring h. Y

.As soon as the cams clear the pin f, the spring l throws the sifter suddenly and forcibly back again, Y

causing the flour to pass through the sifter. Having thus fully described my invention,

' What I claixn asnew, and desire to. secure vbyv Letters Patent, is-

1. lhe sifter J, with pins fg and spring h, in combination with the cams or inclines It k on the cogwheel H, substantially as and for the purposes herein set forth.

2. I he combination of the box A, hopper-bottom B., hopper D, toothed-cylinder E, sitter J, and wheel H, providedl with cams or inclines k k, all constructed and arranged to voperate substantially as andfor the purposes herein set forth.

'In testimony that'I claim the foregoing I have hereunto set my hand this 25th day of February, 1871.

'. OLIVER I). MYERS.
